I set up a multi-site network and installed the membership plugin. Then I created a subdomain site. Within that site I used the membership plugin to create a membership just for that site.
However, it isn't behaving as expected. For one, the logged in user can switch between being on the subdomain site to being on the main site. Also, when I enable the membership plugin on the subdomain site it seems to also enable it on the main site, even though on the main site I disabled it.
Is there any relationship between the membership plugin on a subdomain with the main site?
I am also trying to protect certain content but it seems there is something going on between the two sites.
